Safety Information
Your Thermolyne furnace has been designed with func-
tion, reliability, and safety in mind. It is the user’s respon-
sibility to install it in conformance with local electrical
codes. For safe operation, please pay attention to the
alert boxes throughout the manual.
Alert Boxes
WARNING
Warning alerts apply when there is a possibility of
personal injury.
CAUTION
Caution alerts apply when there is a possibility of
damage to the equipment.
NOTE
Notes alert the manual user to pertinent facts and
conditions.
HOT SURFACE
Hot surfaces alert you to a possibility of personal
injury if you come in contact with a surface during
use or for a period of time after use..

Warnings
WARNING
To avoid electrical shock, this furnace must:
1. Use a properly grounded electrical outlet of correct voltage and current handling capacity.
2. Disconnect from the power supply prior to maintenance and servicing.
3. Have the door switch operating properly.
To avoid burns, this furnace must:
1. Not be touched on the exterior or interior surfaces during use or for a period of time after use.
To avoid personal injury:
1. Do not use in the presence of flammable or combustible materials ; fire or explosion may result.This
device contains components which may ignite such material.
2. Refer servicing to qualified personnel.
3. This warning is presented for compliance with California Proposition 65 and other regulatory agencies
and only applies to the insulation in this product.This product contains refractory ceramic, refractory
ceramic fiber or fiberglass insulation, which can produce respirable dust or fibers during disassembly.
Dust or fibers can cause irritation and can aggravate pre-existing respiratory diseases. Refractory ce-
ramic and refractory ceramic fibers (after reaching 1000°C) contain crystalline silica, which can cause
lung damage (silicosis).The International Agency for Research on Cancer (IARC) has classified re-
fractory ceramic fiber and fiberglass as possibly carcinogenic (Group 2B), and crystalline silica as car-
cinogenic to humans (Group 1).
The insulating materials can be located in the door, the hearth collar, in the chamber of the product or under the
hot plate top.Tests performed by the manufacturer indicate that there is no risk of exposure to dust or respi-
rable fibers resulting from operation of this product under normal conditions. However, there may be a risk of
exposure to respirable dust or fibers when repairing or maintaining the insulating materials, or when otherwise
disturbing them in a manner which causes release of dust or fibers. By using proper handling procedures and
protective equipment you can work safely with these insulating materials and minimize any exposure. Refer to
the appropriate Material Safety Data Sheets (MSDS) for information regarding proper handling and recom-
mended protective equipment. For additional MSDS copies, or additional information concerning the handling
of refractory ceramic products, please contact the Customer Service Department at Barnstead|Thermolyne
Corporation at 1-800-553-0039.

Introduction
Intended Use
The Type F62700 furnace is a general laboratory and
heat treating furnace. For optimum element life, it is sug-
gested that this furnace be used for applications requir-
ing temperatures from 400°F (204°C) to 1600°F (871°C)
for continuous use, or temperatures from 1600°F (871°C)
to 1832°F (1000°C) for intermittent use. Continuous use
is operating the furnace for more than 3 hours and inter-
mittent use is operating the furnace for less than 3 hours.
The unit consists of: 1) muffle heating chamber, 2) a mi-
croprocessor control and 3) a door interlock relay for
user safety.
General Usage
Do not use this product for anything other than its in-
tended usage.
Principles of Operation
The furnace chamber incorporates a heating element
that is embedded into the side walls and top and back of
heating chamber. The ceramic fiber oval muffle with four
heating surfaces creates even heat distribution within the
chamber. The temperature is controlled by a micropro-
cessor control with a type K Chromel/Alumel Thermo-
couple. A fan is provided in the furnace to provide forced
air cooling for the temperature controller. A door safety
switch removes power to the heating elements whenever
the furnace door is opened.
Single Set Point Temperature Controller
One of the furnace’s controllers is a single set point con-
trol, with programmable over temperature protection
which enables the user to bring the furnace up to a pre-
set point and hold the temperature.
Introduction
6
4 Ramp & 4 Dwell Programmable Controller
This controller consists of a microprocessor based three-
mode (Proportional, Integral, Derivative), programmable
temperature controller with “Fuzzy” logic capability, pro-
grammable over-temperature protection and appropriate
output switching devices to control the furnace.The digital
readout continuously displays chamber (upper display) and
setpoint (lower display) temperatures unless the “SEL” but-
ton is depressed.
The programmable control can be used as a single setpoint
control or as a programmable control.
